How soluble is this Citrus × limon oil in different solvents?
Soluble in ethanol and fixed oils; insoluble in water. Practical handling MediumBehaviourEthanol (90-95%)Soluble; the usual carrier for flavour and fragrance workFixed / carrier oilsSoluble; standard for massage and cosmetic oilsWaterInsoluble; needs an emulsifier or a solubiliserGlycerin / propylene glycolLimited; use a solubiliser or pre-dilution in ethanolBecause the oil is insoluble in water, water-based formulations need a proper emulsion system. G4S states the observed solubility on the COA so your formulator can size the solubiliser load.
Which production standards and quality specifications does this Citrus × limon oil comply with?
This distilled cultivar oil has no dedicated ISO monograph, so G4S releases it against ISO 855:2003 (oil of lemon) used as the reference specification — this distilled cultivar oil has no dedicated ISO monograph, with the enterprise specification built on the GB/T essential-oil test-method series.

What factors influence the price of this Citrus × limon oil?
Four factors drive the price, and G4S explains them on every quotation.Grade — the measured marker profile and how tightly it sits inside the release window.Raw material — single-cultivar peel cost and crop conditions in the sourcing season.Volume and pack size — larger fills cost less per kg to pack and handle.Certification and testing — organic, Halal/Kosher or third-party testing add cost.Currency and freight are quoted separately from the FOB price. An annual framework (LTA) is the practical way to stabilise price across a season.
What natural and purity claims can I make for Citrus × limon oil?
The claim chain is documented, not asserted.Identity — Citrus × limon 'Rosso', Fruit peel, Steam distillation, declared on the COA.Process — solvent-free steam-distilled extraction; no fractions or carriers added.Analytics — the batch GC-MS fingerprint must match the natural profile of the cultivar.Traceability — the batch number links the oil to the orchard lot and the COA.That supports "100% natural", "undiluted" and "solvent-free" claims. "Organic" needs a certified lot. Stable-isotope or enantiomeric analysis can be added through accredited labs for premium contracts.
How is this Citrus × limon oil tested for heavy metals and pesticide residues?
Every lot is screened before release; nothing ships without passing. Test panel GroupItemsHeavy metalsPb, As, Cd, Hg, Cu (GB 5009 series)Pesticide residuesMulti-residue screen against destination-market MRLsMicrobiologyTotal plate count, coliforms, mould and yeast, pathogens (GB 4789 series)Solvent residueNot applicable — the process is solvent-free; verified where a buyer requires itLots above any limit are blocked. Buyers can name a specific panel or request third-party verification, and the results are added to the shipment documents.
